T 0 all whom it may concern:

Be it known that I, EDWARD C. Cosronya citizen of the United States, residing at Skidmore but llVlD 1n the count or? Holt a v j to and State otniissourl, have invented new and useful Improvements in Machines for Forcing Gears or Other Articles from a is specifica tion.

pable of forcing a shaft from a device attached thereto and more particularly to .my copending application filed Uctobere, 1920. v

'The primary object of this invention is to simplify the gripping mechanism so that the same may bequiclrly associated with the device to be forced from the shaft. An object of the invention isto provide specially lesigned hooks that may readily engage behind a pulley and hold'thesame against movement during the forcing of the shaft from the pulley by my improved mechanism.

. Another object of the invention is to provlde means capable of generating excessive power for forcing a shaft in a direction to be removed from a device secured thereto in combination with means for holding the de vice against movement. p

A feature of the invention is the novel manner of constructing the hooks and associating same with the frame so that the same may be quickly moved into position to properly engage the device to be removed.

lVit-h these and other objects in view the invention will be better understood from the following detailed description taken inconnection with the accompanying drawings wherein: Y i

F 3 is atop planvicw.

detach ably con uprights but keyed thereto, as illustrated at 5, is a, plunger, shown in this particular case as a worm 6. This worm'is moved by the sleeve 7 screw threaded theretoand havinga gear 8 meshing with the drive gear '9 that in turnis connected to a shaft 10. This shaft '10 may be. operated in any suitable manner but :tor'the purpose of illustration i have shown the handle 11 so that the gears may be manually operated. As far as I have proceeded it will be seen that by oper- I ating the handle 11 the sleeve will be rotated through the gear connection thereby giving longitudinal movement to the plunger or worm. It will also be noted that the worm is held against rotational movement due to the keyed connection, therefore, the end of the plunger is more properly associated with the shaft 12 that is to be forced from the pulley 13 or other device. To increase-the effective engagement between the end of the shaft 12 and the worm a specially designed "pin 14 may be detachably mounted in the socket 15 formed into the end of" the worm.

In this particular instance I have illustrated a plurality of devices detachablyconnected to the front upright so as to readily swing into poslt-ion to effectively engage the device that is to be forced from the shaft. In this particular instance I have ..iIIustrated the pulley 13' and, therefore,.l provide, hook member 16, the hook portion 17 of which engage around the peripheral portion of the pulley. The opposite ends ofthe hooirs are bifurcated and pivotally connected to the bolts 18 as illustrated at 19. These bolts 18 are clamped to the uprights by the nuts Any number of bolts may be distributed" around tlie front upright so that various de-f vices may be detachably secured thereto, de pending upon the work to be performed. I

From the foregoing description taken in connection with the accompanying drawing it will be apparentthat'l provide a machine of such a character that the same may be readily associated with various devices connected to a shaft so that said devices may be mechanically forced from the shaft;

It is, of comrse,to be understood thatthe' device that is connected directly [to the pulners than illustrated-and besides the device .may be used 'in combination with other do not desire to be limited in any manner.

I ley may be constructed in various other man- Again referring tothe drawings lllllStl'htexcept as set forth in the claim hereunto apmounted in holes in the irzune, nuts on the pended. bolts engaging opposite sides 01 the frame Having thus described my invention what. for clamping the bolts to the frame, and a 10 I claim is: plurality of hooks each having a pivotal A machine of the character described coin connection with a, bolt. prising a frame, pressure exerting means In testimony whereof I affix my signature. supported by the frame, bolts reniovably EDXVARD G.
